Machine for manufacturing felt  cloth



THOMAS BUTLER, OF NORWALK, CONNECTICUT.

MACHINE FOR MANUFACTURING FELT 'CLOTI-I.- i

Specification of Letters Patent No. 17,828, dated July 21, 185'?.

To all whom it may concern:

Be it known that I, THOMAS B. BUTLER, of Norwalk, in the county of Fairfield and State of Connecticut, have invented a new and useful Improvement in the Mode of Depositingthe Fibers of the Wool Diagonally in Making Felt Cloth; and I do hereby declare that the same is described and represented in the following specification and drawings and the letters of reference marked thereon.

In order to enable others skilled in the art to make and use my invented improvement, I will proceed to describe its construction and use, referring to the drawings, in which the samecletters indicate like parts in each of the figures.

The nature of my invention consists in the traverse of the apron drum, the apron and its drum ceasing to revolve until the trailing angle of the fibers is reversed, and after such reversal, continuing the traverse in connection with the apron frame and also in combination with a simultaneous traverse in an opposite direction of a transfer roll,

` which receives the fibers from the doer cylinder-whereby the fibers are trailed diagonally upon the apron bat in a more perfect manner than by the Bloodgood patent, of which Iam one of the assignees, or by any other devise for trailing them heretofore known.

In the accompanying drawings, Figure 1, is an isometrical View, Fig. 2, a side view, Fig. 3, an opposite side view, Fig. 4, a top view, and Fig. 5, a sectional view of roll or drum D and gearing.

A, is the doffer cylinder, B, thetransfer roll which receives the fibers from the doffer.

C, C, are pressure rolls resting upon B, D, and moving freely with them, keeping the passing fibers in position.

l D, D, are the apron rolls or drums, F the frame in which the other parts are arranged, F', that portion Qfl the frame which is hung by the jointl G, having friction rollers in the legs of the end next the doffer, to permit an easy vibration.

E, E, are the rolls of the lower apron, lI-I, H, the u per or bat apron, I, I, the lower apron Ywhic revolves in contact with the inferior surface of the upper one, to keep the bat in place.

J is a cam secured to the doffer cylinder, which in the working machine is secured upon the shaft of the doffer cylinder outside of the frame.

K, isa lever having its fulcrum, L, attached to the frame of the carding machine and placed at a proper distance between the rolls B, D.

K has a clutch on the end which works in the collar c, and another clutch just back of the fulcrum L, working into the clutch collar m, on the shaft of the roll B. A

In Fig. 5, a, isa hollow shaft, b inside shaft, c, a clutch collar secured on the end of shaft b, d, is a chambered boX, e, is a collar fitted loosely in the chambered boX d, and on the shaft a, and secured in its movement to the shaft, b, by a key or pin, f, allowing the shaft b, to move back and forth, more or less, as may be desired, by a slot cut in the shaft a. g, g, g, g, are clutch wheels, one on each end of the apron drum D, and one on each end of the shaft a. These clutch wheels are to be placed at such distance apart as may be necessary, in order that the drum D, may not revolve while passing from one connection to the other; nor until the trailing angle of the fibers is reversed.

' The operation of the machine is as follows:

When the doffer cylinder is put in motion,"

and the sliver of bers is combed from its surface, it passes over the transfer roll B, which revolves at a suitable speed, and on to the apron, II, as the latter is revolved bythe drum D. The end of the lever lc is moved at the same time by the lcam'J, and the rolls B and D are vibrated or traversed by it, in o posite directions, which deposits the sliver ci) fibers diagonally upon the bat.

The advantages ment are twofold.

First, by traversing the apron drum D without revolution until the trailing angle of the fibers is reversed, a sharp angle is made by them, and the curved or serpentine deposition of the fibers incident to every other trailing device, is avoided.

Second, by vibrating the apron simultaneously with and in an o posite direction from that of the transfer roil B, the latter is required to be traversed a much less distance and does not stretch or tear the fibers as they pass from the doer cylinder.

gained by this improve-` I do not claim the trailing of the bers of frame F', substantially as described and for Wool upon the bat apron diagonally by the purpose set forth.

means of a traversing roll, for that is covered 2. I also claim the traverse ofthe apron H, by the patent issued to John II. Bloodgood. as described, in combination with a simulta- 5 But neous opposite traverse of the transfer roll, 15

I claim and desire to secure by Letters B, as speoilied.
